cosworth running on 3
my cossy started running on 3 cylinders today, number 2 is down, the rest is fine,, i have tried new plugs,leads,cap,rota arm, there is power going to the injector, tried different injectors, and tried the ecu, done a compression test and thats all fine reading 140 on number 2.
i am stuck with things to change, any help would be great,
can someone help me?
